Magic Mouse Teardown 

Step 1 - 

• Ladies and gentlemen, children of all ages, welcome to 
the Wonderful World of Gadget Magic Teardown 
sponsored by iFixit. 

• We have a special guest tonight in the audience. From 
Cupertino, California, it is our pleasure to introduce the 
world's first mouse to use Apple's revolutionary Multi- 
Touch technology, the Magic Mouse. 

• Let us, at iFixit, be the first to welcome you, Magic 
Mouse, to the grandest stage of them all, please just 
stand there and let us admire you in all your infinite

Step 2 

• Now now Magic Mouse, no need to be modest, let us 
tell the audience a bit about yourself. 

• The Magic Mouse is composed of an aluminum base 
topped off with a smooth multitouch panel, giving it a 
lustrous buttonless appearance. 

• Unlike Apple's previous mouse, the Mighty Mouse, the 
Magic Mouse relies completely on gestures to enhance 
the user's experience. 

• Scroll in any direction with just one finger, swipe 
through web pages with just two fingers thanks to the 
powerful technology of momentum scrolling, where the 
speed is calculated by the rate of the gesture. 

• Oh Magic Mouse.'re so magical! 

Step 3 

• For our next trick, we will need a volunteer from the 
audience. ..yes, you, Magic Mouse. ..well come on up 

• Ladies and gentlemen, the following 
teardown features stunts performed by 
professionals or under the supervision of 
professionals. Accordingly, iFixit must insist 
that no-one attempt to recreate or re-enact 
any stunt or activity performed on this 

• With the public disclaimer out of the way, we can now 
begin tearing down the Magic Mouse. 

• Batteries are included. They're plain ordinary Energizer 
alkalines. We're surprised Steve doesn't have Apple- 
branded batteries, maybe he's been too busy working 
on other things to notice. ..perhaps a tablet.. .maybe 
Steve. ..yes??

Step 4 

• Alakazam! Wow, at $69, the Magic Mouse isn't cheap 
You would think for $69 the Magic Mouse would 
actually be capable of performing magical acts 

• To meet their earnings target for next 
quarter, Apple needs to sell about 164 
million Magic Mice. (However, we've been 
told Apple sells some other products too). At 
that rate, it'll be about nine years before 
everyone in the world has a Magic Mouse. 


Step 5 

• Let's get inside and find the magic amulet that gives the 
Magic Mouse its mighty powers. Not surprisingly, 
copious amounts of magical glue stand between us and 
our goal. 

• We used an iPod Opening Tool to pry the mouse out of 
its shell.

Step 6 

• The glue didn't want to let go, but we overpowered it 
with a flick of our magic wand. Screws would have 
been a lot easier to get apart (and much nicer to put 
back together). 

• There's not much Aluminum in the mouse, we weighed 
just 10 grams. That's compared to 37 grams of plastic 
and 47 grams of batteries. Nearly half the mouse's 
weight comes from the two AA batteries. 

Step 7 

• Open sarsaparilla! Open Saskatchewan! Open 
septuagenarian! Open saddle soap! ... OPEN SESAME! 
Now that was easy enough. 

• Here we receive our first glimpse of magic, (aka orange 
capacitive touch sensors). 

• The top of the mouse is connected to the main board 
and power via a single large ribbon cable.

S Step 8 

• The top of the mouse is translucent. Maybe Apple 
should make a backlit mouse. 

Step 9 

• After prying up the black plastic internal frame, we 
finally get an unobstructed view of the sensors. 

• From the Apple logo up, the entire surface of the 
mouse is covered with capitative touch sensors.

Step 10 

• The brains. 

• The average mouse brain weighs .4 grams. 
The brains of the Magic Mouse weigh 9 
grams. That means the Magic Mouse is 
22.5 times smarter than your average 
mouse. Who knew? 


Step 11 

• Here's the Broadcom BCM2042A4KFBGH chip that 
allows the Magic Mouse to talk to its host. 

• This is a BCM2042 "Advanced Wireless 
Keyboard/Mouse Bluetooth Chip." 

• According to Broadcom, "By integrating all components 
within today's mouse and keyboard into the BCM2042, 
low system costs can be achieved to approach the 
price points of legacy-wired mice and keyboards." 
Apparently Apple missed that memo.

Step 12 

• Magic Mouse, RIP. Another mouse killed in the name of 
science. We didn't break anything, but gluing it back 
together will be challenging. Update: We put it back 
together and it still works! 

• We'll be taking apart the iMac that came with our Magic 
Mouse next. Follow @ifixit on twitter and we'll keep you
